Problems solved by technology

The voice coil motor can achieve a wide range of deflection of the mirror under the input of small power consumption. However, due to the small output force and low stiffness of the voice coil motor, the response speed of the system is limited, and the continuous relative movement of the coil and the

Abstract

An electromagnetic actuating two-dimensional rapid deflecting mirror system comprises a reflector module, a movable table module and a fixed table module, wherein the reflector module, the movable table module and the fixed table module are connected in sequence; the movable table module comprises a permanent magnet assembly and a supporting board assembly; the fixed table module comprises an electromagnet assembly; the permanent magnet assembly and the supporting board assembly are fixedly connected; the electromagnet assembly is powered on to generate a magnetic field to drive the permanent magnet assembly to move; the supporting board assembly deflects along the horizontal axis of the supporting board assembly under movement of the permanent magnet assembly; the supporting board assembly deflects to drive the reflector module to deflect. The reflector module deflects due to the drive torque of the permanent magnet and the electromagnet, supply voltage is low, motion stroke is large, and the hysteresis and creep are avoided. Meanwhile, the position of the fixed table module does not change in the whole process of driving the reflector module to deflect, and the whole system is more stable and reliable.

Description

technical field [0001] The invention relates to a two-dimensional fast deflecting mirror, in particular to an electromagnetically actuated two-dimensional fast deflecting mirror system which generates driving torque through the force of a permanent magnet and an electromagnet to cause mirror deflection. Background technique [0002] The two-dimensional fast deflecting mirror is a kind of optical scanning device, which can realize beam scanning, beam positioning, and target tracking. It is one of the key devices in the application fields of laser radar, adaptive optics, and space laser communication. [0003] The working principle of the two-dimensional fast deflection mirror is that the driver generates angular displacement or linear displacement, and drives the mirror attached to it to realize angular two-dimensional deflection. [0004] In the existing two-dimensional fast deflection mirror system, widely used driving modes are voice coil motor driving mode and piezoelect...
